Abstract
The cyanine distortion of doubly charged ethylenes leading to twisted molecular halves connected by a C-C single bond includes tetrakis(p-di methylaminophenyl)ethylene, which on twofold oxidation with iodine inc reases its twist angle omega from 19 to 53 degrees and its central C=C bond length from 135 to 150 pm as predicted by PM3 calculations.
